PEG is frequently used to preserve waterlogged wood and other organic artifacts that have been salvaged from underwater archaeological contexts, as was the case with the warship Vasa in Stockholm,and similar cases. It replaces water in wooden objects, making the wood dimensionally stable and preventing the warping or shrinking of the wood when it dries.In addition, PEG is used when working with green wood as a stabilizer, and to prevent shrinkage.
